mtg cards like animate dead (Card) Return enchanted creature card to the battlefield under your control and attach this Aura to it Animate Dead (Retro) [Judge Gift

To see play in Cube, it would need trample and haste (and would likely still just barely make the cut)

From Hardened Scales for one-cost to increase it by one +1/+1 counter when they arrive to four mana 4/4 Golgari colored dork called Corpsejack Menace that doubles them

Few players today will own these cards in paper, but how much would it cost you to become one of those people

I saw some lists running Goblin Bombardment to generate value out of Gravecrawler and Undead Augur, but still, I am not sold yet

This approach was endorsed by SQUARE ENIX

Its slow and inefficient in some decks, while its a good stabilizer in others
